PULVERIZER AND HARRow.

7 Application filed November 1, 1887. Ser'al No. 253,999. (hi model.)

To all whom it 'may concern.- Be it known that I, ALBERT HoLMEs TRIPP, a citizen of the United States, residing at Rago, in the county of Kingman and State of Kansas, have invented a new and useful Improvement in Pulverizers and Harrows, of .which the following is aspecification,

My invention relates to an improvement in pulverizers and barrows, and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and claims. 7

In the accompanying drawings, Figure 1 is a side elevation-of a harrow and pulverizer embodying my improvements; Fig. 2 is a top plan view of the same. Fig. 3 i's a vertical longitudinal sectional view of the same, taken on the line as x of Fig. 2. Fig. 4. is a detached perspective view of one of the headblocks. Fig. 5 is a similarview of one of the cutters. A represents a pair of transverse parallel bars, which are connected together at their ends by means of a pair of depending headblocks, B. V

0 represents the tongue, which has its rear end secured in dovetailed recesses made in the upper sides of the bars Aat the'centers thereof.

D represents a pair of hounds which connect 1 the front bar A to the tongue 0. Erepresents a rockshaft which is journaled transversely on the upper sides of the tongue and of the hounds and has its ends turned downward to form arms F. From the upper side of the rock-shaft, at a suitable distance from one end thereoh projects a lever-arm, G. H represents a segmentaldetent which connects one of the hounds with one of the bars A, and is provided on its inner edge witha series of notches adapted to be engaged by the lever-arm G, and thereby secure the rock-shaft at any desired position.

.1 represents a rectangular har-row frame which comprises a pair of parallel bars, K, connected togetherat their ends by bars L. The latter are provided at their centers, on their outer sides, with projecting studs M, on which studs are journaled anti-friction rollers N, andthe said anti-friction rollers extend into a pair of downward and rearward inclined nal slot, T. U represents the whifflelree, which is. an particularly pointed out in .the-

sides of the head-blocks B. r

P represents a pair of links which connect the front side of the barrow-frame to the arms F of the rock-shaft, and It represents a pair'of links which connect the rear side of thel1ar row-frame to the links I. I I

On theunder side of the tongue is secured a strap, S; which is provided with a longitudi; 6o

ranged on the under side of the tongue, between the same and the upper side of the strap,

and is provided at its center with a depending eyebolt, V, which extends downward through 6 the slot in the strap and is connected to the, 7 front side of the barrow-frame, at the center thereof, by means of a link, W. I

X represents a pair of singletrecs which are pivotally connected to the ends of'the whiflietrees in the usual manner, and Y representsa neck-yokesecuredto thefrontendofthetongue. To the rear end of the tongue is attachedla rearward and upward inc1inedstandard,"Z,

which supports the seat A for-the driver. '7 5 On the front side of each bar K of the har row-frame is bolted ametallic plate, B, The

said bars K are provided in their front sides I with a series of vertical openings, as shown,

the openings in thefrontbarK being arranged ,80 1

out on line with those in the rear bar.- 0 represents a series of cutters whichiare' curved, as shown, and have their lower edges 7 sharpened. The said cutters are each pro vided at their front upper ends with spring- '85 The operation of my invention is as follows: 5;

'Whenthe lever-arm G is turned forward to the position indicated in Fig. 1, the arms'F of; the rock-shaft E cause'the links I to permit the barrow-frame to descendand the'anti-'fric-' tion rollers of'the said barrow-frame move grooves, O, which are made on the opposing downward in the inclined grooves O of the head-blocks, and thereby lower the harrowframe to the ground. The links R,which connect the rear side of the barrow-frame to the links P, keep the barrow-frame at all times in a horizontal position, so that the cutters on the under side of the harrow-frame will be kept at work in the soil. The link which connects the barrow-frame to the whiffletree causes the draft to be exerted directly on the harrowframe, and thereby relieves the other parts of the machine of strain.

The coils D, which are provided with the cutters, cause the latter to be kept at work when the harrow-frame is lowered, but per unit them to rise slightly when they encounter unyielding obstructions, and thereby prevent the cutters from becoming broken. By having the cutters swiveled to the bars of the harrow they are adapted to turn obliquely to the line of draft when they encounter stones or small stumps or other obstructions, and thereby the said cutters are enabled to pass around such obstructions without being injured thereby. When the lever G is turned to the position indicated in Fig. 3, the rock-shaft E is turned so as to cause its arms F to draw upward on the links 1? and forward on thelinks R, and thereby cause the barrow-frame to be elevated from the ground, so that the cutters are out of contact with the ground and the en tire weight of the machine is borne by the supporting-wheels, which are journaled on spindles that project from the outer sides of the'head-blocks. The slotted strap in which constructed will be found of great service in pulverizing rough and uneven ground and in placing sod land and stubble fields in condition to be planted.

Having thus described my invention, I claim- 1. The combination of the sulky-frame having the depending head-blocks provided with the inclined grooves O, the harrow-frame having the studs or projections at its ends engaging the said inclined grooves, the rock-shaft j ournaled on the frame and having the leverarms, the longitudinally-movable whifiletree, the links connecting the said lever-arms to the barrow-frame, and the links connecting the harrow-frame to the whifflet-ree, whereby the shaft is'applied directly to the barrow-frame, and whereby the latter may be raised or lowered under the sulky-frame, substantially as described.

2. The combination of the sulky-frame having the depending head-blocks provided with the inclined grooves 0,-the barrow-frame having the studs or projections at its ends engaging the said grooves, the rock-shaft journaled on the sulky-frame, having the lever to turn it to any desired position, and provided with the lever-arms F, the links P, connecting the front side of the harrow-frame to the said lever-arms F, and the links R, connecting the rear side of the barrow-frame to the links 1?, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
